Took rad off to decorate. Put back on. Back panel heats up ok after bleeding but front does not heat at all. Have bled front and back panels. Air came out of back and it is heating ok. Nothing came out of front. Not even water. What is going on?
turn off radiator valves at both ends, screw vent out of rad , push a fine wire or needle into vent hole, it may be blocked , screw vent back into rad before opening valves, vent rad.
